SCREEN-WIRE BINDER.

Application filed September 20,1926. Serial No. 136,499.

This invention relates to a novel method of attaching a screen to the frame therefor to:

gether with a'novel instrumentality for accomplishing this purpose.

The method of securing screen to the frame therefor has been to preliminarily fasten the edges of the screen to the frame by means of any suitable inst'rumentality such as staples or tacks or by means of a strip of wood insertable in a groove provided therefor in the frame portion of the screen, the edge of the screen being confined underneath the inserted stripof wood. When the screen was secured in place it was then the practice to apply a thin strip of wood or other suitable material over the edge of the screen to conceal the irregularities resulting from the operation of attaching the screento the frame."

The operation in the past has been somewhat difficult to perform, requiring usually the Work of skilled mechanics and in addition thereto has taken an unduly long time due to the number of steps in the-operation.

avoiding of the undesirable features con-- nected with the screen industry as pointed out in a preliminary paragraph.

Still another objectis the provision of a novel instrumentality by means of which a screen may be secured to the frame and the edge thereof concealed from view in a single operation. g g

A further ob ect is the provision of a str p for simultaneously securing a screen to the frame thereof, and concealing the edge of the screen strip of a durable nature which may be employed for securing a screen to a frame therefor, and which may be employed indefinitely without injury thereto.

In accomplishing the objects above pointed out a strip is provided having a plurality of downwardly projecting points and a plurality of circular apertures at spaced intervals thereon. The screen is laid out on the frame,

1 the points extended" through the mesh ofthe 'tion is not meant to indicate that this screen and into the wooden portion of the frame, said strip being secured in place by the employment of a plurality of wood screws, each one of said screws extending through one of the circular apertures pro-" vided in the strip.

The invention is capable of several modifications, which modificationstogether' with additional features and objects of the invention will be pointed out with some particu larity in thefollowing description and may become apparent from a consideration'of the drawings which are furnished in connection therewith, in which drawings, v

Figure 1 is a fragmentary view of a screen showing one form which the invention may take; Y Figure 2 is a sectional View taken on the line 22 on Figure 1 looking in the direction of the arrows;

, Figure 3 is another form-which the invention may take; i

I Figure 4 is a sectional view taken on the line 4-4 of Figure 3; Y

Figure 5 is a view showing another form which the strip may take and I Figure 6 is still another form in which the strip may be -manufactured in accordance with the invention. e

Reference may now be'had to the accompanying drawings, particularly to Figures 1 and 2, which embodiment; of the. invention will be described first, butthis order of selecis the preferred form of the invention.

In Figures 1 and 2 numeral 10 refers to the upper portion of the frame and numeral 11 the side portion thereof, a screen 12 being supported thereon by means of strips l3and 14 which are held in place by means of screws 1515. The strips 13 and 14 are each provided with an upraised marginal portion, this marginal portion on the strip l4 beingfplainj 1y shown in Figure 2 and beingdesignated by A still further object is the provision of a the reference character 16. V

particularly from one edge of the inside edge of the marginportion 16 are triangular proj ections or tangs 17 '(Figure 2) The triangular' projections 17 are formed by cutting two. sidesof the triangle from the strip preferably contiguous with the upraised marginal'p'ortion 16. The cutting of the strip in this manner leaves a triangular opening. therein designated by the reference characters 18-418, so

- 1.00 V Depending downwardly from thestrip, Y

that the triangular tang 17 struck therefrom is articulated as a continuation of the margin al upraised portion 16 to enable the penetration thereof without bending. This arrange ment affords the articulation of the tang 17 incident to impressing the upraised marginal portion 16 in the strip 14, thereby precluding the necessity of weakening the line of jointure to the tang with the body of the strip owing to the initial bending thereof.

There is a novel method. employed. in as sembling the screen, but this method will. not

be described until after the other forms which the strip may take and which are shown in .Figures 3. to 6 inclusive have been described.

In the embodiment shown in Figures 3 and 4 the screen frame is designated by the reference characters 10 and 11 and the screen by the reference character 12. The strip therein represented and designated by the reference character 20 is flat with the exception of downwardly extending projections 21 and 22 (Figure 4), said downward projections being formed from the strip by incising the same in the manner indicated by the dotted lines in Figure 3. In this way the projections 21 will all be on theleft hand side of the strip and the projections 22 on the right hand side of the strip. The same construction is obt ained of course whether the strip 20 is on the side of the frame or at the top or bottom thereof. The reference characters 21 and 22 are employed to designate the projections on the side members simply for purposes of clear- 'ness since it is by means of a horizontal sectional view that the projections are indicated in Figure 4.

Where the flat form of strip is employed a corner cap 23 is secured at the intersection thereof at the'corner, said corner cap being secured to the frame by means of screws 24-24. Where the mitred form shown in Figure 1 is employed it is of course unnecessary to employ a corner cap.

In the form shown in Figure 5, pro ections similar tot-hose shown in Figures 3 and 4 are employed but an upraised marginal portionis employed, designated 14: and being of siniilar shape as the marginal portion designated 14 in Figures 1 and 2. The bottom as shown in Figure 6 is flat and is provided with the normal circular aperture for accommodating screws for securing the strip to the frame, but the projections thereon are formed on the margin of the strip instead of in the center thereof. The teeth in Figure 6 are designated by the reference character 25.

. Each one of the strips shown in Figures 5 and 6 may be employed in exactly the same manner asshown in Figures 1 and 3, since the 7 strips readily lend themselves to this form of use without the necessity of any modification whatsoever.

In assembling the screen, the screen portion 12 is laid out over the frame and the strips are brought into place. Before securing the strips to the frame the downward projections thereon are caused to engage the edge of the screen and a gentle pressure is applied thereto to stretch the screen upon the frame sufiiciently to get a taut effect. The

screws 15 are then inserted in the apertures provided therefor and quickly driven home by means of any usual form of screw driver. When the four strips on a screen have been secured to the frame the finished screen is 1 ready for use and if at any time after the completion thereof the screen portion becomes-damaged or worn all that it is'necessary to do isto remove the screws and apply a new portion of screen. The screws can readily be returned into the same holes in the frame, thus avoiding unnecessary. wear to this member.

The strip is preferably made of metal but other material may be used. WVhere the strip is made of metal it is obvious that the downwardly extending projections could readily be cut from the material itself in the manner shown in the drawings. However, I contemplate the provision of separate projections,

no limitation being necessary as to the manner in which the projections are made. The invention contemplates the use of other material besides metal in which case the projections could very nicely be made of metal and embedded in the material of the strip in any suitable manner. For example, a strip might be made of hard rubber and a species of padded projection employed, with the head portion of theprojection member embedded in the rubber before the vulcanization thereof. V I i This is only an example as of course there are any number of materials which could be employed in accomplishing the invention. The only requirements are that the projection be downward from theunder side of the binder strip and be of such a character that it will accomplish the purpose. It is within the province of the present invention to make the projections sufliciently long and sharp so that they can be embedded in the frame ofthe screen without the necessity of employing screws or other fastening means.

Among the advantages of the binder strip which is the subject matter of the present invention is the fact that it is a time and trouble saver since with its use the screen wire can be attached more easily and more quickly than by old methods. It also serves as a stretcher, enabling the workman to get the wire properly in place with less efiort than in the old way. y i

It takes the place of a molding and makes the use of a separate molding unnecessary and hence saves this item ofexpense in screen making. It fastensthe wire more securely than staples or tacks which have been em ployed to a large extent erenow.

In addition, the simplicity and durability of the binder strip makes it easy to operate and hence it may become a practical convenience to an unskilled Workman at the same time lasting indefinitely even in the hands of the unskilled.

In the description of the invention it has been necessary to refer to the binderstrip somewhat in detail but it is not meant to limit the invention by such details, the scope of the invention being defined by the appended 0 mm. s

ginal portion impressed in said strips, tangs struck in said strips to constitute a continuation of said marginal portion to engage said foraminous material, and fasteners for detachably securing said strips to said frame members.
